Xiaolu (Iris) Zhu received the Bachelor of Engineering degree in Electrical Engineering in 2006 from Beijing University of Posts and Telecommunications, Beijing, P.R. China. During the period of 2007- 2008, she obtained the Master of Science degree in Electrical Engineering from the University of Calgary, Alberta, Canada. She has published three papers in journals and three in proceedings of conferences. At present, she is working as a software developer in the Institute for Biodiagnostics (West), National Research Council of Canada, Calgary, Alberta, Canada. Her research interests are digital signal and image processing as well as biomedical imaging. In her spare time, she loves to swim, draw, and travel. Rangaraj M. Rangayyan is a Professor with the Department of Electrical and Computer Engineering, and an Adjunct Professor of Surgery and Radiology, at the University of Calgary, Calgary, Alberta, Canada. He received the Bachelor of Engineering degree in Electronics and Communicationin 1976 from the University of Mysore at the People’s Education Society College of Engineering, Mandya, Karnataka, India, and the Ph.D. degree in Electrical Engineering from the Indian Institute of Science, Bangalore, Karnataka, India, in 1980. His research interests are in the areas of digital signal and image processing, biomedical signal analysis, biomedical image analysis, and computer-aided diagnosis. He has published more than 140 papers in journals and 220 papers in proceedings of conferences. His research productivity was recognized with the 1997 and 2001 Research Excellence Awards of the Department of Electrical and Computer Engineering, the 1997 Research Award of the Faculty of Engineering, and by appointment as a “University Professor” in 2003, at the University of Calgary. He is the author of two textbooks: Biomedical Signal Analysis (IEEE/ Wiley, 2002) and Biomedical Image Analysis (CRC, 2005); he has coauthored and coedited several other books. He was recognized by the IEEE with the award of the Third Millennium Medal in 2000, and he was elected as a Fellow of the IEEE in 2001, Fellow of the Engineering Institute of Canada in 2002, Fellow of the American Institute for Medical and Bio[1]logical Engineering in 2003, Fellow of SPIE: the International Society for Optical Engineering in 2003, Fellow of the Society for Imaging Informatics in Medicine in 2007, Fellow of the Canadian Medical and Biological Engineering Society in 2007, and Fellow of the Canadian Academy of Engineering in 2009. He has been awarded the Killam Resident Fellowship thrice (1998, 2002, and 2007) in support of his book-writing projects. Dr. Anna L. Ells is an ophthalmologist, with dual fellowships in Pediatric Ophthalmology and Medical Retina. She has a combined academic hospital-based practice and private practice. Dr. Ells’s research focuses on retinopathy of prematurity (ROP), global prevention of blindness in children, and telemedicine approaches to ROP.
